This skill teaches how to implement zero-cost abstractions in Rust to achieve compile-time polymorphism with zero runtime overhead.
Refactor a small Rust example to replace a trait object with a generic implementation and compare the performance and binary size.

Rust generics provide zero-cost abstractions through compile-time monomorphization and static dispatch, eliminating the runtime vtable lookup overhead inherent in dynamic trait objects.
Static dispatch inlines generic calls at compile time with zero runtime overhead, whereas dynamic dispatch uses trait objects and vtable lookups that introduce a runtime performance penalty.
Monomorphization generates specialized code for each generic type parameter at compile time, enabling aggressive inlining but potentially increasing final binary size due to code duplication.
Choose generics for polymorphism in performance-critical paths to leverage static dispatch, and reserve trait objects for scenarios requiring dynamic sizing or heterogeneous collections.
No, implementing static dispatch and zero-cost abstractions relies entirely on standard Rust tooling, generics, impl Trait, and trait bounds without requiring any external dependencies.
